MICROMERITICS: Particle Size and Zeta Potential Analyzer
The new NanoPlus instrument uses photon correlation spectroscopy and electrophoretic light scattering techniques to determine particle size and zeta potential. The instrument can measure the particle size of samples suspended in liquids in the range of 0.1 nm to 12.3 μm with sample suspension concentrations from 0.00001% to 40%, and a sensitivity for molecular weight to as low as 250 Da. Duel correlators, log-scale for larger particles prone to time decay and linear scale for small particles, can provide high sensitivity measurements in multi-component samples.
This instrument also reportedly has the ability to perform highly accurate zeta potential measurements of sample suspensions in the -500 mV to +500 mV range. Patented FST technology uses a transparent electrode to minimize path length and reduce multiple scattering effects. This technology permits accurate zeta potential measurement in a wide concentration range of 0.001 to 40%, unique to the NanoPlus, eliminating the need to dilute samples.
